Customizing your Sideline number:
If there is a certain word or digits you'd like in your number, delete the area code, then enter it at the top to find what's available!
*The characters can only be placed in the last four digits of the phone number
If there aren't any numbers matching your area code, numbers containing the characters will appear from other area codes. You can try shortening the word or a variation of what you're looking for to see more results.
Once you've chosen your number, you will see the letters within your number as well as the digits below for the complete phone number
In the infobar at the top of your inbox, your new number with the characters you chose will appear.
Important: Be sure to enable permissions in Sideline to ensure you get the most out of your Sideline application!
Once you reach the 7 days, your Sideline Subscription will begin. For $9.99/month, you can feel secure knowing you'll never lose your new number.
If you have any questions or trouble setting up your new account, please let us know and we'd be happy to help!
Please note: Sideline is designed to be used as a second number for your mobile device and relies on your mobile service for managing communications. Therefore, you will need to use your Carrier cell phone number when registering for your account. Using a Voice over Internet Protocol (VoIP) number, or a number not associated with your device will result in the inability to register for an account and an inferior experience as Sideline is not designed for that use case.
